SB 3.12.15 — The most powerful Rudra, whose bodily color was blue mixed with red, created many offspring exactly resembling him in features, strength and furious nature.
SB 3.12.16 — The sons and grandsons generated by Rudra were unlimited in number, and when they assembled together they attempted to devour the entire universe. When Brahmā, the father of the living entities, saw this, he became afraid of the situation.
SB 3.12.17 — Brahmā told Rudra: O best among the demigods, there is no need for you to generate living entities of this nature. They have begun to devastate everything on all sides with the fiery flames from their eyes, and they have even attacked me.
SB 3.12.18 — My dear son, you had better situate yourself in penance, which is auspicious for all living entities and which will bring all benediction upon you. By penance only shall you be able to create the universe as it was before.
